Good News for Residential Home Owners!
Homeowners in City of Cape Town areas may be relieved to know that financial assistance is available if a high water bill is caused by an underground or hidden leak. The City allows qualifying customers to apply for a rebate, provided certain conditions are met.
This benefit applies not only to domestic households, but also to schools, churches, charities, old age homes, and organisations supporting vulnerable or physically and mentally challenged individuals.
Before submitting an application, property owners must first confirm the presence of a leak by conducting a simple water meter self-test. If a leak is detected, immediate action is essential—repairs must be carried out by a qualified plumber without delay. The rebate typically covers up to three billing months during which the leak occurred, helping to significantly reduce unexpected costs. In some cases, this period may be extended if the leak went unnoticed due to estimated billing by the City. Acting quickly and following the correct process ensures the best chance of approval, making this a valuable relief option for homeowners facing unusually high water charges due to hidden leaks.
